WebFeb 21, 1994 · Introduction To Commutative Algebra. This book grew out of a course of lectures given to third year undergraduates at Oxford University and it has the modest aim of producing a rapid introduction to the subject. It is designed to be read by students who have had a first elementary course in general algebra. On the other hand, it is not intended ...
WebMay 19, 2016 · The best book to have is Atiyah Macdonald, but it leaves a lot to the exercises and doesn’t do homology. A decent book that fills in a bunch of the details is Kaplansky or Sharp (Sharp may not be so nice). Miles Reid wrote a book called Undergraduate Commutative Algebra that focuses on it’s use in algebraic geometry. WebThey then define the tensor product as a ring D = B ⊗AC and want to make it an A - algebra. For that they must define the structural morphism A → D and they claim that it is given by the formula a → f(a) ⊗ g(a) .This is false since that map is not a ring morphism. The correct structural map A → D is actually a ↦ 1B ⊗ g(a) = f(a ...
